This problem is known and documented in the partman-lvm TODO file. This is easily reproducible with partman-auto-lvm: 1) Install guided LVM 2) Clear partition table, e.g. [1] 3) Install guided LVM again I have a patch for partman-auto-lvm but I am not sure if this is reproducible with manual partitioning or not, so no patch for plain partman-lvm yet.
